RAZOR.

To all w ham it may concern Be it known that 1,,BUTLER AMES, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Razors, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates particularly to metallic blade of an instrument, say a razor, to its support or handle; and may be said to reside in a suitable structure making use of magnetism in attaining this purpose.

The advantages of such a structure are that it does away with the necessity of using screw connections formerly employed, the parts may be assembled or taken apart with great ease and speed; there are no small parts to be dropped and lost; and the magnetic lines of force, while the blade is in position. flow through it with a beneficial effect of improving the cutting qualities of the blade.

In the drawings illustrating the principle of my invention and the best mode now known to me of embodying the same in operative structure, Figure 1 is an elevation partly in section of a razor embracing my invention; Fig. 2 shows an end view of the same; Fig. 3 is a plan of it; Fig. 4 illustrates an enlarged detail, one pole piece of a magnet provided with cooperating parts for attaining the object of my invention; Fig. 5 is a perspective view showing the manner of assembling or demounting the razor blade and its co-acting members.

A horseshoe magnet 1 of such size as to be conveniently grasped in the hand, has legs 2 which say one-quarter ofan inch in diameter, and one inch apart. They are made of magnet steel, and then hardened the desired amount, but before they are so hardened, each pole piece of the magnet, in the direction of its length, has a threaded hole provided for the reception of a metallic flat-headed retaining screw 3 later to be described. A ring 4 of soft iron having the same diameter as the legs of the magnet, abuts the end of each leg, while a cross bar 5 of brass or other nonprovided with safety fingers 5, is mounted. upon, and unites these end portions of the 'magnet'; the under and Specification of Letters Patent.

upper sides of the safety bar being recessed to. recelve respectively the rings and the flatheaded screws 3; the tops of the heads being flush with the top surfac of the safety bar. Permanently fixed in the longitudinal axis of each screw is a round nosedguide and lock pin 6, which necessitates having spanner holes in the screw head. A thin rectangular double razor blade 7 with two holes registers with the guide and lock pins 6; as does a lock cap 8 of soft iron, the cap being narrower and longer than the blade, while the blade is narrower than the safety bar with its protecting fingers 5. In short,

the above apparatusdescribed is a safety razor provided with a ma etically rather than mechanically secured lade.

It will be observed that the magnet, rmgs, screws, guide pins and bar are for all practical purposes permanently assembled for use and form a unitary structure; while the lock cap and blade are manually separable.

When the parts of the complete magnet are m operative position, the magnetic lines of force flow from one pole of the magnetto the other, that is to say, for example, from the leg, through the ring, screw, guide pin, cap and razor blade, and the guide pin, screw, ring of the leg.

The guide pins rigidly prevent lateral and longitudinal movement of the blade and cap with relation to the legs of the magnet, while the strength of the magnetic field is suflicient to hold the blades in operative positionagainst the safety bar.

If the blade is to be removed, the ends of the cap are grasped between the thumb and first finger, and, against the magnetic attraction the cap may be removed, and then by a similar operation the blade may be disengaged from the guide and lock pins, and the. safety bar. To removably secure the blade to the magnet a reversal of the steps would accomplish that end.

Desiring to protect my invention in the broadest manner legally possible, what I claim is: w

1. A U-shaped magnet having two adjacent pole pieces; a metallic blade; a bar of non-magnetic material mounted upon the pole pieces said magnet to serve as an abutting surface for said blade; a cap of magnet1c material serving with the blade as an armature for the magnet;

means to prevent the longitudinal and lateral movements of iaid blade and saidcap in relation to said 2. A'magnet having'two adjacent, sepa- 5 rate, soft iron pole pieces; a bar of non magnetic material extending across and being recessed to receive said pole pieces; a flat headed screw with spanner holes Whereby each pole piece and each end portion of 10 the bar may be secured to their respective I leg of the magnet; a pin centrally mounted inthe axis of eachscrew; a metallic blade with suitable holes for said pin to engage; and a cap of magnetic material als'o aengaged' by said pin, and serving as an armature for the magnetic circuit to confine the blade in abutment with the non-magnetic In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
